Dinuclear Ni2-Schiff base complex-catalyzed asymmetric 1,4-addition of β-keto esters to nitroethylene toward γ 2,2-amino acid synthesis
A homodinuclear Ni2-Schiff base 1 complex (1-10 mol%) promoted the catalytic asymmetric 1,4-addition reactions of β-keto esters and an N-Boc oxindole to nitroethylene, giving products in 98-75% ee.
